Hey Christina. For mine, I baked round cakes, desending in size, I think maybe 9", 8", 7".... then for the very top, I baked in a small pyrex bowl. I really stink at carving a 'sphere', so I always rely on my pyrex bowls. LOL I just used the normal household type cake pans that are 1 1/2" in depth, because I didn't want a huge amount of cake. I think that I actually used 2 of the 9" for the bottom layer to get the height that I wanted for the door.

However, the next beehive cake that I make, I want to do the more modern type of beehive. I plane to bake a sheet cake and then cut and stack so that it will resemble the white "box" that is used for keeping bees. For the lid of the box, I plan to use a silver dust over the white fondant. HTH

CWR41 your right it would be helpful but I am not doing the common beehive type cake. I looked and did not find the info i was looking for. My husband has what is known as a top bar beehive. It looks like V shape when your looking at from the end. Then there are wooden slabs running across the beehive. It's not like the box bee hive that people think of when they think of bee hives that bee keepers use.
